No the AEB A4 was just to mention that I'm familiar with the tuning aspect.
I've seen discussion about wideband conversions other places in the forums too, but do you know of a good how to thread about it, do I need a new ECU?
As for the fuel issue. It might be a hardware issue, but all temp sensors read ok values, and then fueling narrows down to injector size and fuel pressure, will check them both. It would just be a good step in my troubleshooting, to load a original base map, to omit a crappy no-name tune for all I know.
Is the definition files for APU motors interchangeble? my ECU part nr does not have any letters on the end 4B0 906 018, while other defintion files i can find ends with two letters.
- To do the wideband conversion you need a new ecu, and O2 sensor. And a few other wires. I'm not sure the DIY is on this forum, but you can Google
- Download some of the other definition files and see if they bring up sensible values for your ecu. Check LDRXN and LAMFA, it's what I do
- There is an auto map locater somewhere on here, by PRJ. Its github link is:
https://github.com/prj/me7-tools, it can find for you a few maps in your bin. Then you can use those map addresses, to calculate the offset with another similar file, and then reverse the process ... I probably can't explain it well e.g:
Your APU:
LDRXN: a
LAMFA: b
KFZW: unknown
Forum APU with known KFZW:
LDRXN: c
KFZW: d
You can do: (c-a) = (d-unknown)
unknown = d-c+a
It's not guaranteed to work.
